A compound having a 7-membered nitrogen-containing ring skeleton represented by the formula (I), which is useful for the prevention or treatment of diseases, in which chymase is involved
and a pharmaceutical containing the same for the prevention or treatment of a disease, in which chymase is involved.
A sustainable, new synthesis of oxalamides, by acceptorless dehydrogenativecoupling of ethylene glycol with amines, generating H2, homogeneously catalyzed by a rutheniumpincercomplex, is presented. The reverse hydrogenation reaction is also accomplished using the same catalyst. A plausible reaction mechanism is proposed based on stoichiometric reactions, NMR studies, X-ray crystallography as well
A method for esterification of one or more carboxylic acid groups in a compound containing one or more carboxylic acid groups wherein the esterification reagent is a diazo-compound of formula:
wherein the R1 and R2 groups of the diazo compound are selected such that the corresponding organic compound of formula:
exhibits a —C—H pKa value between 18 and 29 as measured in DMSO. Specific reagents and methods for esterification are provided. The esterification reagents provided exhibit high selectivity for esterification of carboxylic acid groups over reaction with amine, alcohol or thiol groups in the compound containing one or more carboxylic acid groups. The method can be used to selectively esterify carboxylic acid groups in peptides or proteins.
